So, in order to find out which ordered pairs are the solutions to the given inequality above, we just have to plug in the given values.
Lets take option A.
2 > -3(0) + 2
2 > 0 + 2
2 > 2 ---- 2 is not greater than 2, which makes this ordered pair not a solution to the given inequality.
So, do the same with the rest of the ordered pairs.
So the ordered pairs that are the solutions would only be options C, E and F. Hope that answer helps.

If Dominik completes a project by himself, it will take him 8 hours. Working with Katarina, it will take them 5 hours. If they w

Marysya12 [62]

The main formula we use here is Work=Rate*Time,

1. The rate (speed of working) of Dominik is

$r_D=1project/8hours= \frac{1}{8}(prj/h)$

2. Let the the rate of Katarina be $r_K=x(prj/h)$

Together they have a rate of $r_D_K$ equal to $\frac{1}{8}+x$ (project per hour)

so $(\frac{1}{8}+x) ( \frac{proj}{hr})*5(hr)=1(proj)$

simplify the units:

$(\frac{1}{8}+x) *5=1$

$\frac{1}{8}+x = \frac{1}{5}$

$x= \frac{1}{5}- \frac{1}{8}= \frac{8-5}{40}= \frac{3}{40}$

so the rate of Katarina is 3/40 (proj per hour)

Now, the rate of Dominik was 1/8 (pr/hr)=5/40 (pr/hr)

In 5 hours Dominik complets 5*5/40=25/40 of the project

Katarina completes 5*3/40=15/40 of the project.
